#### Problem 1: Newton's Second Law of Motion

A 2222 kilogram wrecking ball is suspended from a cable and is moving in the vertical (up or down - it doesn't matter). The acceleration of the ball is \(3.4 \, m/s^2\) straight up. Which equation best represents Newton's Second Law? (Assume “up” is the positive direction.)

**Options:**
1. \( T = (2222)(3.4) \)
2. \( T + 21775.6 = (2222)(-3.4) \)
3. \( T - 21775.6 = (2222)(3.4) \)
4. \( T - 3.4 = 21775.6 \)

#### Problem 2: Static Friction and Applied Force

A force is applied to a 24 kg object and presses it against a wall. This force is just great enough to hold the object in place (to prevent it from sliding down the wall). If the coefficient of static friction between the object and the wall is \(\mu_s = 0.27\), then find the applied force.

What is the magnitude and direction of the gravitational force that you exert on the Earth? Consider your answer to part a. 2. Contact Forces¹: Besides gravity, nearly all other forces we will encounter in this course are contact forces, which means that the two objects must be touching for the objects to exert forces on each other. Normal Force: When a surface is touching an object, the surface exerts a force on the object that is perpendicular to the surface and pushes into the object. This is called a "normal" force (normal means perpendicular in math). The harder the surfaces press against each other, the larger the normal force.²
